Offshore Fixed and Floating Structures Course — studying from Ireland
Ireland's maritime sector spans shipping services, offshore energy, marine research and sports boating, with ports such as Dublin, Cork and Shannon Foynes supporting trade and logistics. The offshore wind and marine renewables sector is growing, creating demand for engineers in structures, marine systems and subsea technology. Marine research institutions such as the Marine Institute contribute to ocean science and offshore technology. Oversight is provided by the Irish Maritime Administration within the Department of Transport and by classification and safety bodies.
Fees for Ireland: €743 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Which bodies in Ireland regulate or recognise marine and offshore engineering professionals?
In Ireland, marine matters fall under the Irish Maritime Development Office and the Irish Maritime Administration, while the Marine Survey Office handles vessel safety. Professional engineering membership is usually sought through Engineers Ireland. SEIUM's qualifications are private and not accredited by these bodies, so they do not grant certificates of competency or professional status.
How do employers in Ireland's marine and offshore sectors view private online qualifications?
Employers in Ireland's offshore energy, shipping and nautical industries generally prioritise certified competencies and sea-going or project experience. A private online qualification may complement your background but is judged at each employer's discretion. There is no guarantee it will be accepted for any particular role.
Can I study this online from Ireland and do I need a visa or to relocate?
You can study from home in Ireland, as the programme is fully online and taught in English, so no student visa is needed to study from home. Programme lengths are 300, 800 or 1,900 hours depending on the course. Fees can be paid in instalments, and employer sponsorship is possible. Each student is assigned a technical tutor.

How you'll learn
Delivered 100% online through the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake period, making it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The software used is Bentley SACS, DNV Sesam, Ansys AQWA, OrcaFlex, USFOS, in free, academic or evaluation versions. The practicals cover real procedures: calculating wave loads on a fixed structure, analysing the motions of a floating unit and planning an offshore installation campaign. Assessment is continuous, module by module, plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Distinguish the types of fixed and floating offshore structures and their fields of application.
Calculate wave, wind and current loads on marine structures.
Analyse fixed structures under extreme and fatigue loads.
Determine the hydrodynamic response of floating platforms.
Apply ISO 19900 and its related standards to structural design.
